As the days turned into weeks and months, Erik's journey became a crucible that forged and reforged his abilities, pushing the boundaries of his powers.
His brain crystal powers, while formidable, appeared to be rendered obsolete in the face of the mounting challenges. As a result, he decided to merge them into something more potent, creating new powers from old ones.
Sharpening and Metallization were the first to be combined, resulting in the ability "Metallic Edge Enhancement." Erik could use this fusion to envelop an object or even a portion of his body in a layer of metal, which he could then infuse with mana to create a sharp edge.
This ability bestowed enormous cutting power compared to before, transforming everything from his fingertips to weapons into instruments of death.
